Abstract
Abstract A hair curling iron and apparatus for heating same are provided. The hair curling iron is comprised of a pair of elongated heat conductive semi-cylindrical tubular barrels having an inner flat surface. The barrels have handles and are pivotally connected together whereby the flat surfaces of the barrels may be brought together enclosing hair between. When closed together, the outer shape of the barrels is round, around which the hair is wound to give a curling effect. The size of the barrels, however, is such that the curling iron can not be readily placed in the heating chamber of a conventional curling iron oven. Thus, the instant invention provides for a heat conducting plate having vertical heat conducting rods to be fixed to the top of the oven in heat transfer relationship therewith. The barrels of the curling iron are hollow and open-ended and fit over the heat-conducting rods whereby the curling iron may be heated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
129 words
A hair curling iron comprising a pair of elongated semi-cylindrical barrels of heat conductive material each having an inner flat longitudinal surface facing the inner flat longitudinal surface of the other barrel, said barrels each having a handle at an end thereof and being pivotally connected, whereby said barrels may be moved apart and together in relation to each other, said inner flat longitudinal surfaces of said barrels meeting when said barrels are pivotally moved together, said barrels further being hollow for a substantial distance along a longitudinal length of said barrels and having an open end opposite said end having said handle, said open end being of sufficient dimension to receive in removable relationship therein a heating element, whereby said curling iron may be heated prior to use.
Claim 2
Dependent Claim
129 words
A hair curling iron comprising a pair of elongated semi-cylindrical barrels of heat conductive material each having an inner flat longitudinal surface facing the inner flat longitudinal surface of the other barrel, said barrels each having a handle at an end thereof and being pivotally connected, whereby said barrels may be moved apart and together in relation to each other, said inner flat longitudinal surfaces of said barrels meeting when said barrels are pivotally moved together, said barrels further being hollow for a substantial distance along a longitudinal length of said barrels and having an open end opposite said end having said handle, said open end being of sufficient dimension to receive in removable relationship therein a heating element, whereby said curling iron may be heated prior to use.
Claim 3
Dependent Claim
22 words
The hair curling iron of claim 1 in which said barrels have an arcuate outer surface opposite said inner flat longitudinal surface.
Claim 4
Dependent Claim
227 words
A combination hair curling iron and heating plate arrangement therefore, said hair curling iron comprising a pair of elongated semi-cylindrical barrels of heat conductive material each having an inner flat longitudinal surface facing the inner flat longitudinal surface of the other barrel, said barrels each having a handle at an end thereof and being pivotally connected, whereby said barrels may be moved apart and together in relation to each other, said inner flat longitudinal surfaces of said barrels meeting when said barrels are pivotally moved together, said barrels further being hollow for a substantial distance along a longitudinal length of said barrels and having an open end opposite said end having said handle, said heating plate arrangement comprising a curling iron oven having a heating chamber for receiving curling irons to be heated and a plate, said plate being heat conducting and positioned on top of said hair curling iron oven so as to receive heat therefrom, said plate supporting a plurality of vertical heat conducting rods, said hollow open-ended barrels being of sufficient dimension to receive in removable relationship said heat conducting rods of said plate, said barrels being adapted to be placed over said rods whereby heat from said oven is conducted to said plate and rods and further transmitted to each of said barrels, whereby said curling iron may be heated prior to use.
Claim 5
Dependent Claim
227 words
A combination hair curling iron and heating plate arrangement therefore, said hair curling iron comprising a pair of elongated semi-cylindrical barrels of heat conductive material each having an inner flat longitudinal surface facing the inner flat longitudinal surface of the other barrel, said barrels each having a handle at an end thereof and being pivotally connected, whereby said barrels may be moved apart and together in relation to each other, said inner flat longitudinal surfaces of said barrels meeting when said barrels are pivotally moved together, said barrels further being hollow for a substantial distance along a longitudinal length of said barrels and having an open end opposite said end having said handle, said heating plate arrangement comprising a curling iron oven having a heating chamber for receiving curling irons to be heated and a plate, said plate being heat conducting and positioned on top of said hair curling iron oven so as to receive heat therefrom, said plate supporting a plurality of vertical heat conducting rods, said hollow open-ended barrels being of sufficient dimension to receive in removable relationship said heat conducting rods of said plate, said barrels being adapted to be placed over said rods whereby heat from said oven is conducted to said plate and rods and further transmitted to each of said barrels, whereby said curling iron may be heated prior to use.
Claim 6
Independent Claim
159 words
A device for heating a hair curling iron having at least one hollow barrel and having a dimension greater than can be received within a heating chamber of a hair curling iron oven, said device comprising a curling iron oven having a heating chamber for receiving and heating a curling iron and a heat conductive plate, said plate being mounted on a top surface of said curling iron oven in heat exchange relationship for receiving heat therefrom, said top of said oven having opposed upstanding flanges at the edges thereof whereby said plate closely interfits between said flanges to provide a secure seating relationship, said plate supporting a plurality of vertical heat conducting rods, said rods being adapted to receive a hollow barrel of a hair curling iron larger than capable of being received in the oven chamber, whereby heat from the oven is conducted to said plate and said rods and is further transmitted to the curling iron.
